Why is there so little precipitation just to the east of the northwest coast? A. The air over this area is dry because most of its moisture fell as precipitation near the coast. B. The water cannot travel long distances from the coast because it is heavier than air. C. The winds on the northwest coast are too weak to carry moisture beyond the northwest coast causing less precipitation in the rest of the area. D. The water near the northwest does not get heated up enough to create the water vapor needed to cause precipitation in the area beyond the northwest coast.

Option - C

The winds on the northwest coast are too weak to carry moisture beyond the northwest coast causing less precipitation in the rest of the area.

Explanation:

There so little precipitation just to the east of the northwest coast just because the ability of the air particles is not of optimum level to carry the required amount of moisture from one part or region to another.

The correct answer would be

Why is there so little precipitation just to the east of the northwest coast?

A.

The winds on the northwest coast are too weak to carry moisture beyond the northwest coast causing less precipitation in the rest of the area.

B.

The air over this area is dry because most of its moisture fell as precipitation near the coast.

C.

The water near the northwest does not get heated up enough to create the water vapor needed to cause precipitation in the area beyond the northwest coast.

D.

The water cannot travel long distances from the coast because it is heavier than air.

Explanation:

The moisture-rich air along the northwest coast loses most of its moisture through precipitation near the coast, leaving drier air to continue to the more eastern parts. As the air over this area is dry because most of its moisture fell as precipitation near the coast, the area just east to the north west coast has so little precipitation.
